1, Dimming txoj cai ntawm LED qab nthab teeb
Txoj cai dimming ntawm LED qab nthab teeb yog tsuas yog raws li cov yam ntxwv dimming ntawm LED teeb qhov chaw. Qhov ci ntsa iab ntawm LED teeb pom kev ncaj qha ncaj qha rau qhov tam sim no, thiab los ntawm kev hloov qhov loj ntawm qhov tam sim no, qhov ci ci ntawm LED teeb tuaj yeem hloov kho. Dimming tshuab feem ntau muab faib ua ob hom: analog dimming thiab digital dimming.
Simulated dimming: Kev hloov ci ntsa iab yog ua tiav los ntawm kev hloov cov zis hluav taws xob lossis tam sim no ntawm LED tsav lub zog mov. Txoj kev dimming no yooj yim thiab ncaj qha, tab sis muaj qhov tseeb tsawg thiab yuav ua rau qee qhov sib txawv xim.
Digital dimming: Los ntawm kev tswj lub xeev ntawm / tawm ntawm LED tsav lub zog los ntawm cov teeb liab digital, kev hloov kho qhov ci tuaj yeem ua tiav. Digital dimming muaj qhov tseeb dua thiab ruaj khov, tab sis tus nqi kuj tseem siab.
2, Dimming txoj kev rau LED qab nthab teeb
Txoj kev dimming rau LED qab nthab teeb feem ntau suav nrog cov hauv qab no:
Phau ntawv dimming: Kho qhov ci ntawm lub teeb pom kev zoo los ntawm kev hloov pauv los yog pob qhov rooj. Txoj kev no yog qhov yooj yim thiab ua tau, tab sis tsis hloov pauv txaus los kho lub sijhawm tiag tiag raws li qhov xav tau tiag tiag.
Tsis siv neeg dimming: Los ntawm kev tswj hwm ntse, qhov ci ntawm lub teeb pom kev zoo tau hloov kho raws li qhov tsis xws li lub sijhawm thiab lub teeb siv. Txoj kev no tuaj yeem hloov kho lub teeb pom kev zoo raws li kev hloov pauv ib puag ncig, txhim kho cov neeg siv kev nplij siab thiab txuag hluav taws xob.
Sensor dimming: Siv cov khoom siv xws li lub teeb pom kev zoo thiab tib neeg infrared sensors, qhov ci ntsa iab ntawm cov teeb pom kev zoo tau hloov kho raws li ib puag ncig lub teeb thiab tib neeg kev ua haujlwm. Txoj kev no tuaj yeem ua tiav kev tswj hwm ntse, txhim kho qhov yooj yim thiab lub zog ua haujlwm ntawm lub teeb pom kev zoo.
3, Daim ntawv thov scenarios rau dimming LED qab nthab teeb
Lub dimming muaj nuj nqi ntawm LED qab nthab teeb muaj ntau yam kev siv nyob rau hauv ntau yam scenarios:
Cov nroj tsuag muaj kev lag luam: Hauv kev lag luam, qhov ci ci ntawm LED qab nthab teeb yog hloov kho raws li kev ua haujlwm ntawm cov khoom siv ntau lawm thiab cov kev xav tau ntawm cov neeg ua haujlwm, uas tsis tsuas yog ua kom lub teeb pom kev xav tau ntawm thaj chaw ua haujlwm tab sis kuj tsis txhob siv hluav taws xob pov tseg.
Kev lag luam thaj chaw: Hauv cov khw muag khoom lag luam, chaw ua yeeb yam, thiab lwm qhov chaw, ib puag ncig zoo thiab txuag hluav taws xob tuaj yeem tsim los ntawm cov tshuab dimming. Piv txwv li, thaum lub sij hawm qis qis qis ua ntej thiab tom qab kev lag luam, lub teeb pom kev zoo tuaj yeem raug txo kom tsim nyog los txo kev siv hluav taws xob.
Cov chaw pej xeem: Hauv cov chaw pej xeem xws li tsev qiv ntawv, tsev cia puav pheej, thiab lwm yam, lub teeb pom kev zoo tuaj yeem kho lub teeb pom kev zoo raws li tus naj npawb thiab kev ua haujlwm ntawm cov qhua, txhim kho teeb pom kev zoo thiab txuag hluav taws xob.
4, Qhov zoo thiab cov teeb meem ntawm dimming LED qab nthab teeb
Lub dimming ntawm LED qab nthab teeb muaj qhov zoo hauv qab no:
Kev txuag hluav taws xob: Los ntawm kev kho lub teeb pom kev zoo, kev siv hluav taws xob tsis tsim nyog tuaj yeem zam tau, ua tiav kev txuag hluav taws xob thiab txo qis emission.
Txhim kho kev nplij siab: Kho lub teeb pom kev zoo raws li qhov sib txawv thiab kev xav tau tuaj yeem txhim kho tib neeg txoj kev pom kev zoo.
Txuas lub neej kev pab cuam: kom dimming yuav txo tau cov load ntawm LED teeb qhov chaw, yog li ncua lawv cov kev pab cuam lub neej.
Txawm li cas los xij, hauv kev siv tswv yim, LED qab nthab teeb kuj ntsib qee qhov teeb meem hauv kev dimming:
Tus nqi: Lub tshuab dimming yuav tsum tau nqis peev ntxiv, suav nrog cov cuab yeej tswj ntse, sensors, thiab lwm yam.
Kev nyuaj siab: Kev siv lub tshuab dimming yuav tsum muaj qee yam kev txhawb nqa thiab kev tu lub peev xwm.
Qhov teeb meem kev sib raug zoo: Ntau hom thiab cov qauv ntawm LED qab nthab teeb yuav muaj teeb meem kev sib raug zoo, thiab cov phiaj xwm dimming tsim nyog yuav tsum tau xaiv.
